Crystal is a bit better than the average cruise line, but in no way is it '6 star cruising' and certainly not worth the extra cost. I don't believe it represents good value for money, and personally wouldn't cruise with them again.
Cabins are really small. We'd booked one for two adults, a three year old in a bed and a baby (6 months) in a cot. The three year old was OK in a chair which folded out into a bed (but I wouldn't want to put a child who was much older than that in there). But when the bed was folded out the table in the room had to go under the dressing table, the chair from the dressing table had to be removed from the room completely and the baby had to sleep in our bed as there was absolutely no room for a cot. This wasn't great, but given the fact we had to pay for the baby when he had nowhere to sleep and no food provided it wasn't acceptable. We were told the lowest category of cabin with a fold out bed available was Cat C. We would have much preferred adjacent cabins with an adjoining door in Cat E but we were told this wasn't available. Very frustrating then that someone we were travelling with was allocated just such a cabin and it definitely did have a fold out bed.
The size of the cabin meant there wasn't enough room for all our clothes -- I think we would have struggled with just two people in the cabin -- but with two children quite a lot of our clothes had to remain in the suitcase under the bed, which we could only get out when the fold out bed was folded up.
